Abstract

The invention discloses a light adjustment system for an LED lamp, and the system comprises an LED drive power module. The interior of the LED drive power module is provided with a voltage control module, and the voltage control module is connected with a light adjuster which is used for tuning the output voltage of the LED drive power module. The output end of the LED drive power module is connected with the LED lamp, and the input voltage of the LED lamp is controlled by the voltage control module. The interior of the LED lamp is not provided with an inductor and a capacitor, thereby solving a flickering problem caused by the resonance of a conventional silicon-controlled switch, an inductor and a capacitor.

Description

technical field [0001] The invention relates to LED lighting technology, in particular to an LED light dimming system. Background technique [0002] At present, the common dimming method of LED lighting is the thyristor dimming method, but the thyristor dimming method often causes flickering problems and limits the adjustable dimming range. Aiming at the problems existing between the compatibility of current thyristor (TRIAC) dimmers and LED dimming, the existing technology is mainly to rectify the LED power drive, but when rectifying the LED power drive, in order to be compatible with the dimmers on the market The optical device needs to add a large number of electronic components, and the heat dissipation of the power supply must be handled by potting glue. After adding a large number of components to the LED power driver, the volume of the power supply will increase, and the cost of the power supply will also increase greatly. In the case of volume and increased cost, th...
